Description

Technical Field

[0001] This utility model belongs to the field of PP roller paper folding technology, and in particular relates to a device for indenting PP material in a filter element without partitions. Background Technology

[0002] A filter media indentation device is a specialized device for processing filter media. Its main purpose is to improve the performance and applicability of the filter media by pressing specific textures or patterns onto it. Some indentation devices only have one indentation roller and one traction roller, so the filter media may vibrate slightly during the conveying process, which may cause errors in the indentation of the filter media.

[0003] The improved indentation rollers consist of two sets, vertically installed on the same vertical plane, which effectively prevents the filter media from shaking during the indentation process. However, since PP material is a thermoplastic material with good plasticity and flexibility, in order to ensure that the filter media receives tension during the transfer to the indentation device and thus be more stable, a diaphragmless filter element PP material indentation device was designed. This device mainly uses the cooperation of pressure roller and driven roller to provide auxiliary support for the filter media during transport. At the same time, the pressure roller can move downwards to press and tension the filter media on the surface of the driven roller, thus ensuring that the filter media receives tension during the transfer to the indentation device and thus be more stable. Utility Model Content

[0022] In the following description, embodiments of the device for indenting PP material in a septum-less filter element according to the present invention will be described with reference to the accompanying drawings. Example 1

[0023] Figure 1-4 This invention illustrates an embodiment of an indentation device for PP material in a filter element without separators, comprising: a fixed support box 2 bolted to the rear side of an indentation device 1; hollow positioning plates 3 bolted to both sides of the fixed support box 2; movable support plates 4 slidably connected to the inner cavities of the two hollow positioning plates 3; a round rod 5 rotatably connected to the inner cavity of the fixed support box 2; the left and right ends of the round rod 5 respectively penetrating to the left and right sides of the fixed support box 2; drive gears 6 welded to both ends of the round rod 5; driven gears 7 welded to the surfaces of both ends of the round rod 5; and a rack 8 meshing with the surface of the drive gear 6; and the left and right sides of the indentation device 1 bolted to the rear side of the filter element 1. A cylinder 9 is fixedly connected to the bolt. The output end of the cylinder 9 is fixedly connected to the front side of the rack 8 by bolts. The front side of the movable support plate 4 is provided with a tooth groove. The surface of the driven gear 7 meshes with the tooth groove. The top of each of the two movable support plates 4 is fixedly connected with a perforated support head 10 by bolts. A spring support plate 14 is welded between the bottom of the movable support plate 4 and the bottom of the hollow positioning plate 3. By setting the spring support plate 14, the bottom of the movable support plate 4 and the inner cavity of the hollow positioning plate 3 can be supported when the movable support plate 4 is in a static state. This makes the movable support plate 4 more stable when supporting the pressure roller 11. Example 2

[0024] Figure 1-4This invention illustrates an embodiment of a device for indenting PP material in a filter element without separators. The device includes: a fixed support box 2 bolted to the rear of an indentation device 1; hollow positioning plates 3 bolted to both sides of the fixed support box 2; movable support plates 4 slidably connected to the inner cavities of the two hollow positioning plates 3; a round rod 5 rotatably connected to the inner cavity of the fixed support box 2; the left and right ends of the round rod 5 extending through the left and right sides of the fixed support box 2; a driving gear 6 welded to both ends of the round rod 5; driven gears 7 welded to the surfaces of both ends of the round rod 5; a rack 8 meshing with the surface of the driving gear 6; and a toothed groove on the front side of the movable support plate 4, with the surface of the driven gear 7 meshing with the toothed groove. The top of plate 4 is fixedly connected to a perforated support head 10 by bolts. The left and right ends of the pressure roller 11 are rotatably connected to the inner cavities of the two perforated support heads 10 respectively. The inner cavity of the fixed support box 2 is rotatably connected to two driven rollers 13. The inner cavity of the hollow positioning plate 3 is provided with a limit groove. The side of the movable support plate 4 opposite to the fixed support box 2 is fixedly connected to a guide positioning block 15. The surface of the guide positioning block 15 is slidably connected to the inner cavity of the limit groove. By setting the guide positioning block 15, the movable support plate 4 can be vertically guided and its position restricted when it slides downward in the inner cavity of the hollow positioning plate 3. This prevents the movable support plate 4 from deflecting when it pulls the pressure roller 11 to slide.

[0025] Working principle: When using this utility model, the user starts the indentation device 1 to transport and process the filter material, which then slides on the surface of the driven roller 13 and drives the driven roller 13 to rotate. At the same time, the cylinder 9 is started to pull the rack 8 to slide, which in turn drives the drive gear 6 to rotate. Under the action of the round rod 5, the driven gear 7 is also driven to rotate. Then, under the meshing of the tooth groove, the driven gear 7 drives the movable support plate 4 to slide downward in the inner cavity of the hollow positioning plate 3. This causes the movable support plate 4 to pull the pressure roller 11 to slide downward in the inner cavity of the fixed support box 2, and the pressure roller 11 presses down and tensions the filter material between the two driven rollers 13. This allows the filter material to be tensioned during the process of being transported to the indentation device 1, making the filter material more stable when transported to the indentation device 1.

[0026] In summary, this device for indenting PP material in a filter element without separators works by starting the cylinder 9, which pulls the rack 8 to rotate the drive gear 6 and the driven gear 7. This, in turn, causes the movable support plate 4 and the pressure roller 11 to slide downwards, and the pressure roller 11 presses down and tensions the filter material between the two driven rollers 13. This achieves the goal of providing tension to the filter material during its transmission to the indentation device 1, making the filter material more stable when it is transported to the indentation device 1.
